Title: Improvements in intra-uterine devices
IPC: A61F6/14
Filed: 1935-06-13
Abstract: 461,348. Intra - - uterine device. MECKSTROTH, L. W. June 13, 1935, No. 17068. Convention date, June 13, 1934. [Class 81 (ii)] An intra-uterine device comprises a head made from a pliable filament such as silkworm gut which extends from an appendage adapted to lie in the cervical canal in a plurality of loops to form lobes lying towards the opposite ends of the fundus, the head being of triangular shape corresponding to that of the uterine cavity. The filament may be interlaced at 40 to form loops 30, 32, Fig. 1, the appendage 36 being wound with silk thread and provided with a rubber sheath 46 and withdrawal thread 48. The appendage may be covered with gold leaf or medicaments or apertured to receive the latter. An additional loop may be formed in the filament to increase the tendency of the loops 30, 32 to move apart. Fig. 5 shows an introducer for the device. The loops 30, 32 of the head are compressed and passed over the grooved end 180, the appendage 36 lying in the channel 182 and the loop 48 engaging a pin 190 on a ring 188 pivoted to a sleeve 186. This ring is slightly larger in diameter than the shank of the instrument so that a wedging action is caused when the operating rod 194 is retracted. Movement of the rod 194 suffices to free the device when it has been inserted. Alternatively, the withdrawal loop is engaged by the hooked end of a contractile spring from which it is freed by rotation of said spring, or the device is elongated and received wholly within a C-shaped barrel, the appendage, preferably rigid, being received by a seat in a slidable plunger. As shown in Figs. 12 and 13, a tubular barrel 238 is slotted at 244 and houses a latch 246 slidable by means of a Bowden wire 248 secured to a rod 250 having an operating knob 252. The loops 30, 32 of the device are held by the latch 246 which can be moved by pressing on the knob 252 causing the shoulder 259 to disengage the loops. The Specification as open to inspection under Sect. 91 is not limited to a device having a head made from a pliable filament. The device may be moulded from pliable material with a triangular head 64, Fig. 3 (Cancelled), having reinforcing ribs 66 and apertures 68. In Fig. 6 (Cancelled), the pliable head 96 comprises lobes 98, ribbed at 99 and connected by threads 100. A plurality of flat lobes may be provided or the head may be channelled so that it can be folded and rolled and encased in a readilv meltable material to form a suppository 124, Fig. 11 (Cancelled), having a rim and a socket for the end 128 of an introducer 130. This is grooved to receive the withdrawing loop 120 which is crossed at 134 and retained by a slidable and rotatable latch 136 retracted by a spring 138. Rotation of the spring and latch by means of a member 140 frees the loop to permit withdrawal of the introducer after insertion of the suppository. Alternatively, the introducer comprises a hollow curved tube which receives the suppository and from which it is expelled by a plunger. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,126,715. Welding by fusion. BRODERNA HEDLUND A.B. 19 April, 1966 [21 April, 1965], No. 17082/66. Heading B3R. In apparatus for welding a seam in a shell, e.g., a tank, a cage 10 enclosing a control place for an operator is carried by a trolley 14, Fig. 1, so as to be movable along the shell and supports a glide carriage 22 mounting one or more welding heads and suspended from a support carriage 112 movable relative to the cage 10 in the same direction as the cage 10. Excess relative movement between the support carriage 112 and the cage 10 automatically results in a correcting movement of the cage 10. Excess relative movement between the guide carriage 22 and the support carriage 112 automatically produces a correcting movement of the support carriage 112. In apparatus for welding horizontal seams in a tank which is built from the top downwards, the trolley 14 is driven around rails 42 at the top of the tank 20 and carries a hoist 24 connected to one or more cables 26 supporting the cage 10 and fixed to a rotatable mounting 34 secured centrally on the top of the tank. The support carriage 112 running on rails 116 mounted in the cage 10 carries cables 110 from the ends of which depend the guide carriage 22 and counterweights 122. The guide carriage 22 is in two parts connected by a horizontal pivot and each carrying a pair of magnetic rollers 48, 50. The rollers 50 are driven and the rollers 48 are steerable by the use of an electric motor which also correspondingly raises or lowers the welding heads mounted on the guide carriage 22. Electrodes are fed from reels 138 on the support carriage 112 and welding powder is supplied to the welding zones and is supported by rubber bands 88 mounted on pairs of pulleys. As the guide carriage 22 is driven along the weld seam, a pivoted arm 132 is actuated by movement of the cables 110 away from the vertical to operate switches controlling movement of the support carriage 112. Should the speeds of the trolley 14 and the support carriage 112 be so different that the carriage 112 actuates a limit switch 115 or 117, the trolley 14 is automatically moved to centralize the support carriage 112 relative to the cage 10. Similar apparatus may be used for welding spiral seams of tanks.

Void [Published under.,Sect. 91 of the Acts]. [Class 102 (i).] In an internal-combustion engine in which fuel is supplied to injection-nozzles by a pump or pumps, a hand-operated pump p, for supplying the nozzles at starting, is inserted in the suction pipe k of the pump or pumps 1, which are adapted to permit flow from the hand-pump to the nozzles. The plunger of the hand-pump controls its own suction port while the valves of the main pump act as discharge valve for the hand-pump, the cylinder of which is in constant communication with the outlet through a groove v. In an engine having a separate fuel pump for each cylinder, the plungers 3 of which are rotatable by means of levers 10 to vary the fuel supply, all the levers 10 being linked together, the plunger of the hand-pump is normally locked by a pin, which is automatically withdrawn when the levers 10 are put in the " stop" position. Each lever 10 is mounted on a sleeve 9 carrying a bar 8, which engages a slot in the plunger 3. An axial slot 14 in the plunger connects the pump chamber with a groove 11 having a helical upper edge 13. When the edge 13 uncovers an inlet port 15, according to the adjustment of the plunger, the fluid is by-passed. When a single pump is employed connected to the cylinders through a rotary distributer, means may be provided for uncoupling the distributer from its driving-gear and rotating it by hand to put the cylinders in. succession in communication with the hand-pump. Alternatively the distributer 21, Fig. 5, may be pushed axially by a lever 31 to bring a groove 33 opposite the openings of the pipes I .. IV of the cylinders, thus putting a groove 30 and the discharge pipe n simultaneously into communication with all the cylinders. Normally the groove 30 communicates with the pipes I..

Filed: 1931-06-15
Abstract: 380,801. Galvanic batteries. BUMKE GES., H. A., 8, Chausseestrasse, and AUTOM SPEZIAL-MASCHINEN GES., 5, B³lowstrasse, both in Berlin. June 15, 1931, No. 17396. Convention date, Aug. 5, 1930. [Class 53.] In a machine for making dry batteries which places the covers on the zinc containers, caps the carbon rods and solders the pole wires to the containers, a conveyer is employed which moves in a straight line and which comprises a movable part 20 which embraces a fixed part 19. The movable part slides on the outer faces of the fixed part and is mounted on arms 21 which are rotatable on crank pins 22 projecting from discs 23 which are rotated by worm wheels 25. The movement of the arms 21 first lifts the conveyer, then advances it and then lowers it again. The cells normally rest on the fixed member 19 but are lifted by the upward movement of the part 20 and are carried forward until the part 20 is again lowered when the cells are again laid on the part 19. Both edges of the movable part are formed as racks to receive the ends of the cells which are first conveyed to a centring device 2 which centres the carbon rod in the zinc container of each cell before the cover is put on. The cell is then conveyed to the device 3 which punches out covers from a cardboard strip and places them on the containers over the carbon rods. The covers are pressed tightly into position by a device 4 and the cells are then conveyed to a capping device 5 and finally to a conveyer disc 11 of a soldering device. The disc 11 carries the cells first past a device 12 for wetting the containers with spirit and then to a device 13 which draws the pole wire into position for soldering and cuts off pieces of the required length. The cells with the wires held in the correct position are then brought up to the soldering device 14 which automatically solders the wires in position. Specification 380,475 is referred to.
